Dissertação apresentada na Faculdade de Ciências e Tecnologia da Universidade Nova de Lisboa para a obtenção do grau de Mestre em Engenharia Informática.Traceability is becoming a necessary quality of any modern software system. The
complexity in modern systems is such that, if we cannot rely on good techniques and
tools it becomes an unsustainable burden, where software artifacts can hardly be linked
to their initial requirements.
Modern software systems are composed by a many artifacts (models, code, etc.).
Any change in one of them may have repercussions on many components. The
assessment of this impact usually comes at a high cost and is highly error-prone. This
complexity inherent to software development increases when it comes to Software
Product Line Engineering. Traceability aims to respond to this challenge, by linking all
the software artifacts that are used, in order to reason about how they influence each
others.
We propose to specify, design and implement an extensible Traceability Framework
that will allow developers to provide traceability for a product line, or the possibility to
extend it for other development scenarios. This MSc thesis work is to develop an
extensible framework, using Model-Driven techniques and technologies, to provide
traceability support for product lines. We also wish to provide basic and advanced
traceability queries, and traceability views designed for the needs of each user
